Health policy precludes neonatal vaccination against influenza. Hence, morbidity and mortality are high under 6 months of age. Lactoferrin may activate diminished numbers of dysfunctional dendritic cells and reverse neonatal vaccine failures. Aluminum hydroxide/ALUM recruits neutrophils that secrete lactoferrin at deposition sites of antigen. We theorized lactoferrin + influenza antigen initiates an equivalent antibody response compared to ALUM. Three-day-old mice received subcutaneously 30 μg of H1N1 hemagglutinin + 200 μg of bovine lactoferrin versus hemagglutinin + ALUM. Controls received hemagglutinin, lactoferrin, or ALUM. After 21 days, sera measured anti-H1N1 (ELISA) and neutralizing antibody (plaque assays). ELISA detected equal antibody production with lactoferrin + hemagglutinin compared to hemagglutinin + ALUM; both sera also neutralized H1N1 virus at a 1:20 dilution (p < 0.01). Controls had no anti-H1N1 antibody. Neonates given lactoferrin had no anaphylaxis when challenged four weeks later. Lactoferrin is a safe and effective adjuvant for inducing antibody against influenza in neonates.

With improving living standards, functional and healthy foods are accounting for an increased share in human food. The development of dairy products that are rich in virgin omega-3 polyunsaturated fatty acids (n-3 PUFAs) has become a topic of interest. Virgin n-3 PUFA milk can provide high-quality protein and calcium, as well as provide n-3 PUFAs to improve human health.

Background: Many protective proteins, including lactoferrin and heavy chain antibodies, are present in camel colostrum, giving it a distinctive composition. Beyond a broad spectrum of pathogens, these proteins demonstrate antibacterial properties.
Aim: The current research assessed the prophylactic properties of camel colostrum against F17.

Hepatocellular carcinoma (HCC) constitutes 90% of liver cancer cases and ranks as the third leading cause of cancer-related mortality, necessitating urgent development of alternative therapies. Lactoferrin (LF), a natural iron-binding glycoprotein with reported anticancer effects, is investigated for its potential in liver cancer treatment, an area with limited existing studies. This study focuses on evaluating LF's anti-liver cancer effects on HCC cells and assessing the preventive efficacy of oral LF administration in a murine model.

Lactoferrin (Lf) is a naturally occurring glycoprotein known for its antiviral and antibacterial properties and is present in various physiological fluids. Numerous studies have demonstrated its antiviral effectiveness against multiple viruses, such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza virus (IFV), herpes simplex virus (HSV), hepatitis B virus (HBV), and human immunodeficiency virus (HIV). Lf, a vital component of the mucosal defense system, plays a crucial role in inhibiting viral infection by binding to both host cells and viral particles, such as the Hepatitis C virus (HCV).
